turn them up by one degree each day until you are
comfortable with the temperatures. You won’t have to adjust
the thermostat further. Any adjustments above these settings
will waste energy and cost you more money.
If your heating system is a boiler with radiators, there will
usually be only one programmable room thermostat to
control the whole house. But you can have different
temperatures in individual rooms by installing thermostatic
radiator valves (TRVs) on individual radiators. If you don’t
have TRVs, you should choose a temperature that is
reasonable for the whole house. If you do have TRVs, you can
choose a slightly higher setting to make sure that even the
coldest room is comfortable, then prevent any overheating in
other rooms by adjusting the TRVs.
The time on the programmer must be correct. Some types
have to be adjusted in spring and autumn at the changes
between Greenwich Mean Time and British Summer Time.
You may be able to temporarily adjust the heating
programme, for example, ‘Override’, ‘Advance’ or ‘Boost’.
These are explained in the manufacturer’s instructions.
Programmable room thermostats need a free flow of air to
sense the temperature, so they must not be covered by
curtains or blocked by furniture. Nearby electric fires,
televisions, wall or table lamps may prevent the thermostat
from working properly.
